Technical Article Boiler Blowdown - Clayton Industries

• The maximum acceptable TDS level in the boiler water – the lower the level the greater the amount of blowdown. • The TDS in the blowdown water – the higher the TDS, the lower the amount of blowdown. • The average load level for the boiler (BHP or lbs of steam per hour). As can be seen from the above, applications with high

Conductivity - A Measurement of Total Dissolved Solids

Conductivity - A Measurement of Total Dissolved Solids Mario C. Uy Raw water contains dissolved impurities commonly referred to as Total Dissolved Solids (TDS). As the water is evaporated in processes such as boilers and cooling towers, the impurities are left behind, increasing their concentration levels in the remaining water.
